The following doesn't work:
fields = [db.cart.id, db.cart.id.count()]
grid = SQLFORM.grid(db.cart,
fields=fields,
left = [db.cart_content.on(db.cart.id==db.
cart_content.cart)],
groupby=db.cart.id)
what's the best way to accomplish this?
I simply wan to count how many items in each cart.
logically db.car.id.count() should really work here, but it doesn't.
greatly appreciate any suggestions on how to do this properly.
